 * @param e  the mouse event./*w ww .  ja  v a 2 s . c  o  m*/
 */
public void mouseDragged(final MouseEvent e) {

    final JTableHeader header = (JTableHeader) e.getComponent();

    if ((header.getDraggedDistance() > 0) || (header.getResizingColumn() != null)) {
        this.renderer.setPressedColumn(-1);
        this.sortColumnIndex = -1;
    }
